[Sequence settings]
[Export as a program sequence]
Check this item to export sequences as programs.
[Audio Settings]
[Channels]
Select the number of audio channels you want to export from the list.
[Quantization Bit Rate]
Select an audio quantization bitrate from the list.
[Ch 1&2] - [Ch 15&16]
Select the channel to output bitstream when outputting audio with the audio
bitstream retained.
[Format]
Select an export format from the list.
[Bit Rate]
Select a bitrate from the list.
[Format]
Select an export format from the list.
[Format]
Select an export format from the list.
[Segment Encode]
Check this item to export a clip of a raw source without re-encoding.
This increases the output speed.
[Quality/Speed]
Select quality from the list.
[Bit Rate]
Select a bitrate type.
[CBR] sets a fixed transfer rate, allocating a fixed number of bits during the
encoding process. Select a bitrate from the [Average] list. You can also enter
a value directly.
[VBR] sets a variable transfer rate, altering the number of assigned bits
according to the complexity of the movement or image quality. Compared
with [CBR], the media volume can be used more efficiently, and this enables
more consistent image quality overall. Select a bitrate from the [Average] and
[Maximum] lists. You can also enter a value directly.
[GOP structure]
For MPEG, a certain number of frames is considered as a group, and opera-
tions such as compression/enlargement and cut editing are performed on a
GOP basis. A GOP comprises “I frame”, “P frame” and “B frame”. The I frame
allows images to be reproduced independently, the P frame is for recording
and reproducing only the differences with the preceding image, and the B
frame reproduces images from the differences in the preceding and following
images. Select I, P and B frame patterns of the GOP from the list. Normally,
select [IBBP].
[I-Frame Only] is comprised of only I-pictures. Editing is made easier, but the
amount of data increases in size.
[Picture count]
Set the number of frames included in a group.
